CommandBarComboBox Event not fired / triggered every time

[TobyG]

Hello

I have a CommandBarComboBox in a Toolbar and one button.

The events works fine in the first Word Document window.

On opening the 2't window the event onyl works for the button.
The event for the combobox will not longer triggered / fired in the 2't
window.
The event works in the 1st window.

Reassining the event does not solve the problem.

any ideas?
workarrounds? I need a DropDown Box.

thanks a lot
